Connect the Information Server DataStage Designer Windows clients to IBM Cloud Pak for Data

Steps

1. Ensure that the Red Hat OpenShift client, oc, is installed on your computer (Windows or Mac). You use the oc client to access the Red Hat OpenShift cluster where Cloud Pak for Data is deployed.  You can also log in directly to the Linux Infrastructure node and use the oc client that is already installed there for this procedure.
2. If you need the oc client, download the oc command-line tool by following the instructions at Get Started with the CLI 3.11 or Get Started with the CLI 4.5
3. Install the client tool and put the directory in which you installed the tool into your path in the OS environment.
4. Ensure that you have an account that is created for you in Red Hat OpenShift so that you can log in and get access to the cluster. Contact the administrator of the system that is running your instance, if necessary.
5. If required, add the IP address and host name for your Red Hat OpenShift system to your hosts file. On Windows, the hosts file is located in: C:\Windows\System32\drivers\etc\
   192.168.1.100 ibm-master ibm-master.cloud master
6. From a terminal or command window, log in to the cluster: oc login https://<openshift cluster>:port. For example:
   oc login https://ibm-master.cloud:8443

1.  Change to the project where <namespace> is the namespace of your cluster where DataStage is installed: 

   oc project <namespace>

2. Back up the configmap ds-proxy-cm setting: 

   oc get cm ds-proxy-cm -o yaml > ds-proxy-cm.yaml

3. Edit the configmap ds-proxy-cm: 

   oc edit cm ds-proxy-cm

   Use vi command to add two lines after the line proxy_pass backend; and save the change:

       
   proxy_socket_keepalive on;
   proxy_timeout 4h;
     

4. Scale down the deployment ds-nginx-proxy: 

   oc scale deploy ds-nginx-proxy --replicas=0

5. Scale up the deployment ds-nginx-proxy: 

   oc scale deploy ds-nginx-proxy --replicas=1

6. Wait and confirm that the ds-nginx-proxy pod is restarted: 

   oc get pods | grep ds-nginx-proxy

1. Download nginx for Windows from http://nginx.org/en/docs/windows.html.
2. Update the nginx configuration file nginx.conf:
   1. Get the value for the place holder <ds-proxy-route>: 

      
      oc get route ds-proxy -n <namespace> -o jsonpath='{.spec.host}'

      where <namespace> is the namespace of your cluster.
   2. Replace the place holder <ds-proxy-route> with the value in the nginx.conf file:

      
      #user  nobody;
      worker_processes  1;
      
      #error_log  logs/error.log;
      #error_log  logs/error.log  notice;
      #error_log  logs/error.log  info;
      
      #pid        logs/nginx.pid;
      
      
      events {
          worker_connections  1024;
      }
      
      stream {
          log_format json_combined escape=json
              '{'
                '"time_local":"$time_local",'
                '"remote_addr":"$remote_addr",'
                '"status": "$status",'
                '"$upstream_bytes_sent":"$upstream_bytes_sent",'
                '"$upstream_bytes_received":"$upstream_bytes_received",'
                '"upstream_connect_time":"$upstream_connect_time",'
                '"upstream_addr":"$upstream_addr"'
              '}';
          #access_log logs/nginx.log json_combined;
          upstream backend {
              server  <ds-proxy-route>:443;
          }
          server {
              listen 31538;
              proxy_pass backend;
              proxy_socket_keepalive on;
              proxy_timeout 4h;
              proxy_ssl  on;
              proxy_ssl_session_reuse on;
              proxy_ssl_server_name on;
              proxy_ssl_name <ds-proxy-route>;
          }
      }

      Note: If the Windows system has the full Information Server suite installed, then port 31538 is not available, so the port needs to be changed to an unused port (e.g. 31537). For example, replace the line "listen 31538' with "listen 31537" in the nginx.conf file.
3. Update hosts file under C:\Windows\System32\drivers\etc by adding the following entry to map is-en-conductor-0.en-cond to localhost.

   
   127.0.0.1   is-en-conductor-0.en-cond
4. Start or reload nginx service if it's already running. In the directory where Nginx was unzipped, run one of the following commands:

• To start nginx service, run: start nginx

timeout client    30m
timeout server    30m
